SPECIFICATION forming part of Letters Patent No. 446,392, dated February10, 1891.

Application iileclAugust 15, 1890. Serial No. 362,092. (No model.)

To all whom zit may concern:

Be it known that I, HUBERT F. PROBERT, of Three Rivers, in the county ofSt. Joseph, State of Michigamhave invented certain new and usefulImprovements in Car-Trucks, of

which the following is a specification, reference being had to theaccompanying drawings.

The object of my invention is to produce a truck that is complete initself, that is adapted to carry interchangeably any sort of body thatmay be attached to it, that is so constructed as to carry its bodyevenly and smoothly without jarring or swaying, and is also soconstructed that the wheels, boxes, and axles may be convenientlyremoved from the truck and afterward replaced without detaching thetruck from its body.

In the accompanying drawings, Figure l is a side elevation of myimproved truck; Fig. 2, a top plan view of the same. Fig. 3 is a view ofa part of one of the side frame-pieces detached. Fig. et is a front viewof a pair of truck-wheels, showing the relations to it of parts of mytruck. Fig. 5 is a side elevation of the frame-work of one side of mytruck detached.

Referring to the letters on the drawings, A

' indicates the side frame-pieces, each of which preferably consists ofa pair of fiat metalbars set edgewise and separated by blocks B or thelike and bound together by bolts O.

D indicates the lower middle bars, each being preferably made of fiatmetal, bent at each end at right angles, and bolted at its ends to theoutside of the frame-piece A.

E indicates the lower end bars, each being preferably made of flat metaland bent at one end at right angles and at the other end at an obliqueangle and bolted at its ends to the outside of 'one of the frame-piecesA.

E indicates a pair of bars that are separated from each other bythimbles and are bolted to the inner side of the bars D and E.

F and Gindicate transverse stays that pass through the frame-pieces Aand the bars D, respectively, and hold the parts rigidly to gether.

H indicates the wheels of the truck, that are carried inside of theframe by axles lin boxes J. rlhese boxes are carried in the spaces be-It may be added that fenders N maybe carried by any suitable means uponthe frame at each end.

The above-described truck is a complete thing in itself, and, being'carried rigidlyupon the axles, is adapted to carry a motor, Where one isused, either upon the axles or frame or to supports secured thereto, asmay be desired, which are adapted to give it a firm and rigid support.

Upon the top of the main frame above described is carried abody-supporting frame P, of corresponding dimensions with the main frameand preferably made of at metal.

Q indicates vertically-sliding brackets that are bolted in pairs to thelower side of theA body-supporting frame P and are adapted to movesmoothly and freely along the outer sides of the adjacent bent ends ofthe bars D and E, as upon ways, and also to bear lat-erally on the outersides of the frame-pieces A. By this means the body-supporting frame iscarried securely upon the main frame, but may move freely in a verticaldirection upon it.

The brackets shown and described are a convenient means' of movablysecuring the body of the frame to ways upon the main frame; but I do notdesire to limit myself to the exact details in this respect. Any sort ofways upon the main frame, and a traveler upon the body-framearecontemplated by my invention.

R indicates springs,A preferably made of metal in spiral form; but anykind of spring may be used. They are distributed along the sides of thetruck in suitable numbers, and are carried in bearings adapted for thembetween the body-suporting frame and the IOO , ing-frame and may bereadily detached from itrwhen it is desirable to change one body foranother.

By means of the construction above described I am able to distribute thesprings between the body-supporting frame and the main frame, so as toattain a very etfective equalization of all motions, shocks, and strainsthat vmay be imparted through the main frame to the bodyesupportingframe and the body carried thereon. By this means and the location ofthe wheels Within the frame I am able to prevent the swaying inotionincidental to many kinds of street-cars, for instance, and thereby tocontribute to the ease and oomfort'of passengers. At the same time I dothis without disturbing the irmness of the parts that carry thecar-motor when lit carriesv one.

What I claim is l l. In a street-car truck, the combination, with itsWheels and their axles, of side frames 'and oars D and E, securedthereto and bent so as to form spaces for the bearings of the axles,substantially as set forth.

2. In a car-truck, the combination, with its frame, Wheels, and axles,of vertical pockets in the frame, adapted to receive the bearings of theaxles, and bars detachably secured to the sides of the pockets forclosing them, whereby ready means for securing and detachingthe framefrom the Wheels, axles, or bearings is provided, substantially as setforth.

3. In a car-truck, the combination, with the main frame, of a body-framecarried thereon, the main frame being provided with bars D and E,secured to it and bent so as to form Ways, and brackets upon thebody-supporting frame, adapted to move vertically upon said Ways and tootherwise hold the body-supporting frame in fixed relations to the mainframe, silibstantially as set forth.

Ll. In a car-truck, the combination, With the main frame', of ayieldingly-supported bodysupporting frame adapted to be carried thereou,the Ways upon the main frame, and brackets upon the body-supportingframe, adapted to travel upon the Ways and While restraining motion inevery other direction to permit free vertical motion of thebody-supporting frame upon the main frame, substantially as set forth. A

In testimony of all which I have hereunto subscribed my name.

HUBERT F. PROBERT.
